Analysis of an Elastohydrodynamic Lubricated Point Contact, User's Manual

Abstract

In this report, a PC-based computer program is described. The computer program calculates the descriptive characteristics of a general elastohydrodynamic (ehd) lubricated point contact typically found in bearings, gears, and cams. The following characteristics of the contact are calculated: 1. The contact maximum and mean Hertzian stress; 2. The contact ellipse dimensions; 3. The ehd isothermal minimum and central film thickness; 4. A thermal film thickness correction factor accounting for the effect of shear heating because of sliding and rolling. In addition, it provides the basic theoretical background and equations used. Keywords: Bearings; Elastohydrodynamic lubrication; Film thickness. (JES)
